Embodiment 1

[0023] The invention provides a method for improving the germination rate of gourd seeds, the specific steps are as follows:

[0024] (1) For gourd seeds with unqualified germination rate to be triggered, if the seeds have a high water content, then dry them naturally or dry them at a low temperature below 25°C until the water content is lower than 8.0%; then choose plump and mature ones. Seeds are packed into mesh bags suitable for gourd seeds, ready for priming.

[0025] (2) Dilute the purchased ethephon water agent with 40% active ingredients with tap water or distilled water; pour about one-third of the tap water or distilled water into the bucket or tank, and then pour the ethephon water agent, Stir with a stick while pouring the ethephon water agent, and finally add tap water or distilled water to dilute, so that the final dilution factor is 600 times the amount of the ethephon water agent, and then stir evenly, then the initiation treatment can be carried out; the seed ...

Embodiment 2

[0031] The invention provides a method for improving the germination rate of gourd seeds, the specific steps are as follows:

[0032] (1) select unqualified germination rate, but plump, mature Yongzhen No. 1 gourd seeds to be triggered, with moisture content within 8.0%, put into mesh bags for the next step of triggering;

[0033] (2) The active ingredient of ethephon is 40% ethephon water agent diluted 600 times to configure seed triggering liquid;

[0034] (3) The gourd seeds to be triggered are mixed with the seed trigger solution at a weight ratio of 1:1 for triggering;

[0035] (4) Initiate soaking gourd seeds for 55 hours, soaking at 15-30°C;

[0036] (5) Spread the induced seeds and dry them in the sun until the water content of the seeds is within 8.0%.

[0037] The configuration of the seed priming solution described in step (2) is configured by directly drinking tap water or distilled water.

[0038] Stir every 6-8h in the soaking process described in step (4).

...

Embodiment 3

[0043] The invention provides a kind of method that improves the germination rate of gourd seeds, specifically comprises the following steps:

[0044] (1) select unqualified germination rate, but plump, mature Yongzhen No. 3 gourd seeds to be initiated, moisture content within 8.0%, pack into mesh bag for initiation of next step;

[0045] (2) The active ingredient of ethephon is 40% ethephon water agent diluted 600 times to configure seed triggering liquid;

[0046] (3) The gourd seeds to be triggered are mixed with the seed trigger solution at a weight ratio of 1:1 for triggering;

[0047] (4) Initiate soaking gourd seeds for 45 hours, soaking at 15-30°C;

[0048] (5) Spread the induced seeds and dry them in the sun until the water content of the seeds is within 8.0%.

[0049] As a preferred embodiment, the configuration of the seed triggering solution in step (2) is configured using directly drinkable tap water or distilled water.

[0050] As a preferred embodiment, stirr...

Abstract

The invention discloses a method for increasing the germination rate of gourd seeds, belonging to the technical field of vegetable seed production. According to the method for increasing the germination rate of the gourd seeds, a seed priming solution prepared from an acide phosphorique is used for soaking the gourd seeds for priming; the method concretely comprises the steps of soaking the seeds in the seed priming solution prepared from the acide phosphorique, and drying for realizing seed priming. After the method provided by the invention is used for priming the gourd seeds having lower germination rate, the germination rate of the gourd seeds can be increased to 85% or above, the germination uniformity of the gourd seeds is obviously improved, the gourd seeds still have qualified germination rate after being placed for three months. The method provided by the invention is simple in operation, high in controllability and low in cost, is capable of effectively priming the gourd seeds, is obvious in priming effect, has better production application value, and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of vegetable seed production, and mainly relates to a method for breaking dormancy of gourd seeds and improving the germination rate of gourd seeds. Background technique [0002] Gourd (Lagenaria siceraria (Molina) Standl) belongs to Cucurbitaceae and Cucurbitaceae. It is widely planted in my country and the temperate and tropical regions of the world. Extensive cultivation makes there is a greater demand for gourd seeds in production. Northwest is one of the main bases for gourd seed production, but due to the special local climate conditions, the seeds harvested have a longer dormant period than those in the south, and the germination rate and uniformity are not enough. However, large-scale production such as anvils and edible gourds requires high germination rate, neat germination, and short dormancy time. Therefore, breaking dormancy has become an important issue restricting the efficient production of...
